FACTS OF INTEREST: There are forty-two species of flying squirrel, found mostly in Asia and Europe, with two species in North America. Flying squirrels do not really fly, but glide after leaping from trees, usually for 20 to 75 feet, but sometimes as much as 150 feet. Flying squirrels steer by tightening and loosening the furred flaps of skin that stretch from their front wrists to their back feet. Flying squirrels are nocturnal. Their big eyes are well adapted to night vision. One of the favorite foods these omnivores search for in the dark is the truffle, a mushroom delicacy.
